Swap in low-flow showerheads and faucet aerators at an invited south Vallejo home

Once an audit lists the leaks and old fixtures, the fix is a wrench and an hour: low-flow showerheads and aerators cut a household's water use by a quarter with no change in comfort. In a neighborhood where water bills bite, that is real monthly money back. Standard: EPA WaterSense fixture specifications; SDG 6 (Clean Water and Sanitation). Proof: Before/after fixture photos plus occupant sign-off Method (EPA WaterSense fixture specifications; SDG 6 (Clean Water and Sanitation).): 1. Confirm the audit checklist with the occupant and gather WaterSense-labeled showerheads, aerators, and flappers. 2. Shut off supply lines and swap each listed fixture, using thread tape on every connection. 3. Replace worn toilet flappers and re-run the dye test to confirm the leak is gone. 4. Run each fixture and check for drips after ten minutes. 5. Photograph each new fixture installed and the signed occupant acknowledgment. Done when: Before/after fixture photos plus occupant sign-off

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 45–90 minutes. Method of record: EPA WaterSense fixture flow-rate + leak audit

Bring

• flow-rate measurement bag + timer
• toilet dye tablets
• moisture meter
• GPS / address
• camera
• tablet / data sheet

Steps

1. 1. Confirm the address; get a staff escort; photograph each fixture group.
2. 2. Measure flow rate at each faucet/shower with the bag-and-timer method; record gallons per minute (gpm).
3. 3. Test each toilet for leaks with a dye tablet (wait 10 min, check for color in the bowl); record flush volume.
4. 4. Inspect fixtures, meters, and irrigation for visible leaks/drips; note each.
5. 5. Read the water meter with all fixtures off; note any movement (indicates a hidden leak).
6. 6. Rank WaterSense fixture upgrades + leak repairs by estimated water/cost savings.
7. 7. Record flow rates, leak results, meter check, ranked measures, and photos into the proof record; sign.

If it does not match the plan

• Meter moving with all fixtures off AND active water damage (wet drywall, ceiling stain, pooling near electrical) -> STOP: possible electrical exposure; keep clear, route to a licensed plumber (and electrician if water contacts wiring). The agent documents, never opens walls.
• Suspected cross-connection / backflow risk (hose-bib, irrigation, boiler makeup) -> flag for a licensed plumber backflow test; potable-water contamination is a health hazard — do not test-operate the connection.
• Toilet dye migrates into the bowl -> flag a leaking flapper/valve for repair.
• Meter moves with all fixtures off -> flag a hidden leak for investigation.
• Faucet > 2.2 gpm or showerhead > 2.0 gpm -> recommend a WaterSense upgrade.
• No electrical/gas work; documentation only — flag suspected pipe damage, do not disassemble.

What counts as done

• Flow rate (gpm) recorded per fixture
• Toilet leak result + flush volume recorded per toilet
• Meter-with-all-off check recorded
• Ranked upgrade/repair measures + photos + address confirm

Proof is measured against these, not judged by taste.
